摘要:

[摘要]目的:利用生物信息学方法构建系统性红斑狼疮(SLE)基因表达亚群。方法:从GEO数据库下载GSE121239GSE65391GSE154851的微阵列数据集,利用R软件对数据集消除批次效应、聚类共识分组、临床特点分析,使用STRING网站对特异性基因所表达的蛋白质构建蛋白质相互作用(PPI)网络图,筛选枢纽蛋白对应的基因,进行GO功能富集分析和KEGG信号通路分析。结果:共获得1 254SLE样本、124例健康对照样本。PPI网络分析显示节点最多的蛋白分别为:STAT3TLR4BRIX1TLR2KEGG分析表明:自然杀伤细胞介导的细胞毒作用、核糖体、线粒体自噬、细胞凋亡、血小板活化、造血细胞谱系、破骨细胞分化、甲型流感等信号通路富集最显著。结论:将SLE患者分成了3个基因亚群,可为该病的诊断、分类及个体化治疗提供潜在的依据。

Abstract:

AbstractObjectiveTo construct the gene expression subgroups in systemic lupus erythematosus by bioinformatics. MethodsThe microarray data sets of GSE121239GSE65391 and GSE154851 were downloaded from GEO database. R software was used to eliminate batch processing effectcluster consensus grouping and analyze clinical characteristics. PPI network map of proteins expressed by specific genes was constructed by using the STRING websitegenes corresponding to pivotal genes were screenedfollowed by GO analysis and KEGG signal pathway analysis. Results1 254 SLE samples and healthy control samples were obtained. PPI network analysis showed that the proteins with the wost nodes were STAT3TLR4BRIX1 and TLR2. KEGG pathway enrichment analysis showed that differentially expressed genes were significantly enriched in natural killer cell-mediated cytotoxicityribosomemitophagyapoptosisplatelet activationhematopoietic cell lineageosteoclast differentiationinfluenza A and other aspects. ConclusionSystemic lupus erythematosus patients were divided into 3 gene subgroupswhich can provide a potential basis for the diagnosisclassification and individualized treatment of the disease.
